Parallel Evaluation of GFS MOS

On July 28, 2010, NCEP implemented a major upgrade
to the Global Forecast System (GFS) model which
serves as input to the GFS-based MOS guidance. MDL ran the GFS MOS in parallel
for 30 days using the operational equations, applied to the parallel GFS model output.
MDL evaluated the parallel GFS MOS
from 14 June - 14 July, 2010, to determine the impacts of these changes to GFS MOS products.
The results are shown below.
